Packaging for food and drink is already benefiting from using nanotechnology methods and devices, such as clay nanoparticles and nanosensors. Nanoclays, molecular barriers, nanocrystals, antimicrobial...

Graphene oxide membranes have been receiving attention for their extremely powerful separation abilities and the ease at which it can be modified, allowing for membrane permittivity to be fine-tuned. These membranes show the potential to be used for water purification, ‘green’ gas purification and greenhouse gas capture.
